RICHARD SRRENLEAF TURNER, oF WORCESTER, MASSACHUSETTS, ASSIGNOR To oRoMrToN & xNowLns LOOM WORKS, OEWORGESTER, MASSACHUSETTS, n `COR- PORATION or MASSACHUSETTS U i t V AUXILIARY SHUTTLE Rox FOR SHUTTLE CHANGING Looms l Application mea August 14, 1930;` Serin no. 15,247. y

shown. The usual picker 15 is'mounted on` a picker stick land is` engaged by the shuttle S as it enters the upper orregula-r `box 11, this `position of the ,parts being shown in Fig. 1.

This invention relates to a shuttle changing loom of the type in which the auxiliary shuttle is received in an auxiliary shuttle box upon the occasion of weft replenishment.

rlhe exhausted shuttle is picked into this auxiliary shuttle box in the usual way, but the shuttle is immediately discharged `from the auxiliary box and from the loom, and no shuttle is ever picked out of the auxiliary shuttle 1n box. Consequently the exhausted shuttle is never acted upon by the regular loom picker after it enters the auxiliary box and it need have no operative relation thereto.

It is the object of my invention to provide means for bringing an exhausted shuttle to rest inthe auxiliary shuttle box independently of any action of the loom picker and for holding the exhausted shuttle in such position until discharged therefrom.

A further object of my invention is to provide means by which an exhausted shuttle will be stopped in a deniteand predetermined longitudinal position in the auxiliary shuttle box, the position being such that the shuttle may be ejected from the box without interfering with the loom picker.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred `form of the invention is shown in the drawings, in which Fig. 1 is a iront elevation of parts of a shuttle-changing loom embodying my improvements 5 F ig. 2 is a similar view, showing an exhausted shuttle received in the auxiliary box;

Fig. S is an enlarged side elevation of my improved shuttle stopping device;

the direction of the arrow Referring to the drawings. I have indicated portions of a shuttle changing magazine M, a lay 10, an upper or regular shuttle box 11 and a lower or auxiliary shuttle box 12. The boxes l1 and 12 are mounted. on a lifter rod 13 and are shifted vertically in the lay l() by the usual box lifting mechanism, not

The parts thus far` described are in general of the usual construction and in themselves form no part of my present` invention, which relates particularly to certain changes embodied in the lower or auxiliary shuttle box l2.

The rear wall of the lower auxiliary shuttle box 12 is provided with serrated blocks 22 and 24 projecting forward therefrom and positioned respectively in the upper and lower rear corners of the shuttle box. Stop members 30 and 31 are provided with serrated rear Surfaces to cooperate with the blocks 22 and 24, and may be secured in adjusted position against the blocks by binding` Screws 33 which extend through elongated slots 34 in the members 30` and 31.

The shuttle-engaging faces of the members 30 and 31 are curved to fit the corresponding end portions of the shuttle S and are preferably faced with strips of leatherBG. The stop members 3() and 31 are so adjusted on the serrated blocks 22 and 24 that they will simultaneously engage the upper and lower end surfaces of the shuttle S and that they will stop the shuttle in correct position for ejection from the auxiliary shuttle box.

The preferred position is indicated in Fig. 2, in which it will appear that the shuttle S is so located by the stopmembers 30 and 32 that the point of the shuttle S does not enter the hole in the picker 15 and consequently does not require to be dragged or forced out of the picker during ejection or upon Shifting movement of the shuttle box.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, other* wise than as set forth in the claims, but what I claim is 1. In a shuttle changing loom, an auxiliary shuttle box, means fixed relative to said box in position to engage a shuttle at each side of the Shuttle point and to positively limit entering movement of said Shuttle into said iii) box, said shuttle-engaging means and said shuttle box having cooperating serrated surfaces by which longitudinal displacement of the engaging means is prevented.

2. In 1a shuttle -Kchanging loom, a yregular shuttle-box, an auxiliary shuttle box `vertical'- ly aligned with said regular shuttle boxand movable vertically into alignment with the active shuttle, means Afixed relative xto said auxiliary "box in position to engage an approaching shuttle at each side of the entering shuttle point and Lto 'positively-limitentering movement of said shuttle into said auxiliary box and to prevent thebpointfof ,theshuttle entering the picker or engaging the picker duri-ng relative vertical movement of said shuttle and pikenand means to adjustably position 4said engaging Vmeans and to hold said vadjusted f'engaging means Ifrom longitudinal displacement.
